Home appliances sold by a shop in one month are given as below:
| Home appliance | Number of home appliances |
| Refrigerator | 75 |
| Television | 45 |
| Washing Machine | 30 |
| Cooler | 60 |
| DVD Player | 30 |
Draw a bar graph to represent the above information.
Solution
In order to draw a bar graph representing the above data, we follow the following steps:
Step I: Take a graph paper and draw two mutually perpendicular lines OX and OY. Let OX as the horizontal axis and OY as the vertical axis.
Step II: Along OX, mark of home appliances and along OY, mark number of appliances.
Step III: Choose a suitable scale to determine the heights of the bars, according to the availability of space. Here, we choose 1 unit length represents 10 home appliances.
Step IV: Calculate the height of various bars as follows
| Home appliance | Height of bars |
| Refrigerator | `75/10` = 7.5 units |
| Television | `45/10` = 4.5 units |
| Washing Machine | `30/10` = 3 units |
| Cooler | `60/10` = 6 units |
| DVD Player | `30/10` = 3 units |
Hence, the required bar graph for the given data is shown below
Scale: 1 unit length = 10 home appliances
